Answer:
<em>firstly</em><em> </em><em>for </em><em>separating</em><em> </em><em>fillings</em><em> </em><em>we </em><em>should</em><em> </em><em>use</em>
<em>magnet </em><em>for </em><em>separating</em><em> </em><em>it,</em><em> </em><em>and </em><em>we </em><em>left </em><em>with </em><em>sulphur</em><em> </em><em>and </em><em>salt </em><em>so </em><em>for </em><em>this </em><em>we </em><em>will</em><em> </em><em>use</em><em> </em><em>water</em><em> </em>
<em>when </em><em>we </em><em>add </em><em>water </em><em>then </em><em>salt </em><em>get </em><em>dissolve</em><em> </em><em>in </em><em>it </em><em>and </em><em>we </em><em>can </em><em>easily</em><em> </em><em>take </em><em>out </em><em>sulphur</em><em> </em><em>again</em><em> </em><em>by </em><em>evaporation</em><em> </em><em>we </em><em>will </em><em>obtain</em><em> </em><em>salt </em>
<em>hope</em><em> it</em><em> helps</em>
Answer:
4.419 g
Explanation:
55 years is 5.5 half lives
200 g * (1/2)^5.5 = 4.419 g
Part 1 : Answer is only B substance is soluble in water.
In this experiment undissolved mass of each substance was measured. According to the given data, undissolved mass of substance B at 20 °C is 10 g while A is 50 g. Since, the initial added mass of each substance is 50 g, we can see that substance A is not soluble in water since the undissolved mass is 50 g.
Part 2 : Substance A is not soluble in water and substance B is soluble in water.
According to the given data, the undissolved mass of substance A remains as same as initial added mass, 50 g throughout the temperature range from 20 ° to 80 °C. Hence, we can conclude that substance A is not soluble in water.
But, according to the data, undissolved mass of substance B at 20 °C is 10 g. That means, 40 g of substance B was dissolved in water. When the temperature increases the undissolved mass of substance B decreases. Hence, we can conclude that substance B is soluble in water and solubility increases with temperature.

Answer:
sp2
Explanation:
Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.
C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is sp2 hybridized.
Hence, the correct answer is "sp2".
